To all whom it may concern:

. Be; it known that I, JOHANN PAPIEZ, a citizen of the German Republic, residing at 1 Landsbergerplatz, Berlin, Germany, have invented certain new and useful Improvements' in Flying Machines, (for which I have filed applications in Germany on August 2nd, 1919, and July 10th,- 1920,) of which the following is a specification.

This invention relates to improvements in flying -machines and more particularly to flying machines with a lifting propeller. The flying machine according to the invention comprises a number of arrangements which greatly facilitate and improve the practical I application of such machines.

These arrangements afiect the lifting pro peller itself andits' drive on the one hand,

and on theother hand they have to do with the members for moving the machine forward and for steering'the same, and with the'cushioning members for preventing serious jolts or shocks when the machine returns to the ground-Q :Inthe accompanying drawing, which discloses the parts of a flying'machine to which body of the machine rests upon feet 5.

These are guided in air cylinders 6 which have small air passages 7 at their upper ends, so that when the machine alights upon the ground and the feet are caused to enter the cylinders, the air in the latter is compressed and partly or gradually escapes through the openings 7. When the machine rises again, the air returns into the cylinders through the openings 7', and the feet; drop or move out again of their own weight. To

ensure uniform movements of the feet they may be connectedto each other by suitable stays.

The lifting propeller 18, and a propeller .11 mounted on the shaft 12 and operating to drive the flying machine forward in the direction indicated bythe arrow, are rotated by a motor in the gear box 15. The propeller 11 is mounted at a considerable distance from the frame of the flying machine, the said distance being about equalto the diameter of the propeller. The lifting propeller 18 is mounted on a vertical shaft at a considerable height above the top of the flying machine. The whole length of the shaft 16 from the frame to the propeller is surrounded by a hollow column 17 which forms an extension of the roof 14.

By the large air space thus provided between the body of the machine and the propeller the air is enabled to pass without hindrance to the wings of the propeller and their efficiency is thus improved.- The efficiency of the advancing propeller 11 is also enhanced ina similar manner by its horizfintal'distance from the body of the mac me.

Arranged at both sides lof the advancing propeller 11 are steeringpropellers 8 and 9 which are driven from the shaft 12' of the advancing propeller 11 in the manner dek scribed below.

Pulled by springs 21' into a wedge-shaped groove 20 (Fig. 3) in the shaft 16 of the lifting propeller 18 is a brake block 19.

The brake block 19 is mounted on a twoarmed lever 22' to whose longer arm a wire 23 (Fig. 1) is attached. This wire is-adapted to be wound onto a roll whichis turned by a crank 25with the aid of-a worm or screw gear. By rotating the *crank the lever 22.m ay be shifted and the brake block thus lifted more or less clear of the shaft 16 in opposition to the springs 21. By this means the propeller, may be regulated so as to revolve at any desired speed, this being particularly important for the gentle alighting of the flying machine.

The shafts,% and 27 of the steering propellers 8 and 9 are mounted upon sliding .members 28, 29, and are generally driven 'with the aid of belts or other transmittin members 30, 31 from the shaft 12 of the advancing propeller 11 which is rotated by the motor. The sliding members 28, 29 which glide in suitable slideways are drawn apart by adjustable spring tensioning devices 32, 33 so that the driving bands or belts 30, :31 are generally taut. The sliding members are each connected to a draw wire 34, 35 which pass over suitable guide rollsi36 to driving rolls 37 each .of which is adapted to be rotated by a crank handle 38, 39 with the aid of a screw gear. The driving belts can thus be slackened so as to ut the steering propellers entirely or part y out of oporation. The crank handles 38, 39' are sit- 4 uated like the crank 25 for regulating the peed of the lifting propeller; so as to bewithin convenient reach of the pilot.

I do not desire to limit myself to the exact construction shown and described, as it is evident that other means along the same lines may be utilized to secure quite, the same results. I

I claim:' 7
